EDIT -- OOOPS! Sorry Darrell -- I inadvertantly edited your post when replying, and couldn't restore it!! I'll go back to moderator's school to get requalified on the new software 
I wear a 43/43 (~size 9). I shift with the lever at the shift pad on my left boot, just about at the joint behind the big toe.
Just to check, I went out and sat on the bike, and realized I unconsciously slide my foot forward as a shift, with the heel going from behind the peg to above (not in front of) the foot peg rubber. Happens so fast I didn't even notice at first. You may want to try this for a week or so to see if you can get comfortable with it.
